Long term and short term trading became my time portfolio as if you have no need to take sl if yours analysis is good just and short term can be hours or days long terms can be more that week upt to weeks but it depend how you calculate your profit as long or short term but for me i always use short term open and close my trades every one or tow days only i think the different between long term and short term in trading is the time if the position period less than one day it considered short term if more than one day it considered long term and also it depend on time frame
